I have 1.35 XR drives and stock Bravo 30p props.
This was a dealer demo boat and they said at Havasu they got it to 103 with stock 32p props.

Mike.
I was just up at powell with my boat over labor day and with my 30s I saw low 80s at a max of say 4700 rpm without a lot of trim.

I know you asked about 496's but my 28' with 525's ran 114. It ran at least 105 no matter the conditions or load.
